This result makes sense intuitively.
If a customer has a good interaction with a customer service agent, it will likely build their trust in their bank because it shows that the bank is responsive and effective.
On the other hand, if a customer has a bad interaction with a customer service agent - or can’t access customer service support when they need it - their trust will be damaged.
Implications
Our data suggests that there are multiple ways for banks to build trust: having good apps and having wide access to branches have worked for different providers.
Having good customer service, though, seems to be a crucial ingredient.
1 The question has the following options: "strongly agree", "agree", "neither agree nor disagree", "disagree" and "strongly disagree". The trust index score is calculated using the following formula: ((% answering strongly agree x 2) + (% answering agree) + (% answering disagree x -1) + (% answering strongly disagree x -2))/ 2. We use this formula to subtract those who distrust a provider from those who trust them, to give additional weight to those answering strongly agree and strongly disagree, and to create a single score to compare sectors and track change over time.
